Watch Scanning Camera for Invisible Bar-code Playing Cards

Watch scan cameras are widely used by poker players. Even more surprising is that the camera can be installed in the strap and dial of the watch.
1. When the camera is inside the strap, when you lift the card, it can scan the barcode marked card;
2. When the camera is inside the watch face, it can scan cards with barcode marks within its working distance.
3. Its battery power lasts for 2 hours.
4. Your watch camera can be customized.
NOTE: Before you place an order or send us your watch, please let us know the distance range you need for your poker game. The distance here refers to the distance between the scanning camera and the marker set. Typically, the dealer prefers shorter distances, while players prefer longer distances.
